I'm currently debating between the two devices and definitely would like to hear some 3rd party opinions. I have a MacBook and an iMac so the streaming from iTunes would be nice, but the conversion of everything to h.264 mp4 would be a daunting task. Where the WDTV I could just take the drive over and I think most of my media would play. I like the hack ability of the ATV, but the portability of the WDTV would be nice for when I get my 56" HD and the smaller one goes into the "boom boom" room. The ATV could utilize an old PC with iTunes and a bunch of TB drives as a server, has or can anyone try hooking the WDTV to a usb port on Mac/Win to see if this can see the media on the machine? Well if anyone can offer some opinions and/or insight it would be appreciated. BTW: for ppl with WDTV how does the 1080p compare to the 720p? I realize on smaller screens (under 50") you really can tell unless you have a trained eye, on the new set we are looking at (around 56" HD DLP Led backlight) I'm just wondering if the 720p from the ATV won't be good enough. Thanks for you help, Derek J.D.
